BDS 4-Inch 4-Link Lift Conversion Kit — Ram 3500 SKU: BDS1676FS | Ram 3500 2019–2024 | 4WD | Gas | 4" Front / 3" Rear | FOX 2.0 Performance Series | Without Factory Rear Overload Leaf

A complete 4-inch 4-Link suspension lift kit engineered for the 2019–2024 Ram 3500 gas 4WD. The 4-Link conversion replaces the factory stamped steel radius arms with high-strength ¼-inch steel brackets and HD upper and lower control arms to correct axle positioning and limit caster change throughout wheel travel. Gas-specific Pro-Ride dual-rate coil springs provide the correct front lift height. A precision transfer case indexing ring and high-clearance transmission crossmember address driveline geometry. Three-inch rear lift via high-strength steel block. FOX 2.0 Performance Series shocks front and rear. Clears up to 35-inch tires. 100% bolt-on.

Gas engine only — diesel Ram 3500 is not supported by this kit. Exhaust modification is required to clear the front driveshaft — this must be completed before or during installation. The vehicle can be driven without the front driveshaft to an exhaust shop.

Installation Notes

Professional installation is strongly recommended. All components are 100% bolt-on. Installation involves front 4-Link conversion, coil spring replacement, steering correction components, transfer case indexing, transmission crossmember installation, and rear block installation.

Exhaust modification: Exhaust modification is required to provide clearance for the front driveshaft. This modification must be performed before or during installation. The Ram 3500 can be driven without the front driveshaft installed to reach an exhaust shop if necessary.

Verify before beginning:

• Rear spring configuration (with or without factory overload leaf)
• Transfer case type (manual T-case requires BDS122422)
• Rear driveshaft type (2-piece carrier bearing requires BDS122406)
• Exhaust modification plan
• ADAS recalibration appointment scheduled

Professional alignment is required after installation. Refer to the current BDS Suspension installation instructions for SKU BDS1676FS for complete procedures, torque specifications, and component-specific instructions.

The Obsidian Take

The BDS1676FS is the purpose-built 4-Link lift solution for the gas Ram 3500 4WD — 4 inches of front lift via a proper 4-Link conversion and gas-specific Pro-Ride coil springs, 3 inches of rear lift via steel block, and FOX 2.0 Performance Series shocks all around for trail-capable damping at this height. The 4-Link conversion is the substantive upgrade here: it replaces the geometry limitations of the factory stamped radius arms with corrected axle positioning and caster control throughout wheel travel. Two pre-installation items need plans before this kit ships: the exhaust modification for front driveshaft clearance and rear overload leaf verification. Get the exhaust shop scheduled and confirm your rear spring pack. Both are simple to address in advance and expensive to ignore after installation has started.

Common Questions

Does this kit fit the diesel Ram 3500?
No. This kit uses gas-specific Pro-Ride coil springs and is designed for gas engine Ram 3500 models only.

Which 2024 Ram 3500 trims does this fit?
Big Horn, Laramie, Limited Longhorn, Tradesman, and Limited. Not all 2024 trims are verified — confirm yours before ordering.

How do I know if my Ram has the factory rear overload leaf?
The factory rear overload leaf spring is an option on some Ram 3500 trucks. Inspect your rear spring pack — if it has three or more leaves, or if your truck was configured with a heavy-duty towing package, you may have the overload leaf. When in doubt, confirm with a shop or your build sheet before ordering.

Why is an exhaust modification required?
At 4 inches of lift, the front driveshaft angle requires exhaust clearance that the factory exhaust does not provide. This modification is required before the front driveshaft can be reinstalled. The truck can be driven without the front driveshaft to reach an exhaust shop.

Do I need the carrier bearing drop?
Only if your Ram 3500 has a 2-piece rear driveshaft with a carrier bearing. Confirm your driveshaft configuration — if 2-piece, BDS122406 is required.

Do I need BDS122422?
Only if your Ram 3500 has a manual transfer case. If equipped with a manual T-case, this shifter extension is required.

Does ADAS need to be recalibrated after installation?
Yes. This kit changes vehicle ride height and suspension geometry. All ADAS sensors require professional recalibration after installation. All recalibration costs are the owner's responsibility.
